METAL WHEEL.

Application filed iaiihafy 17, 1920. Serial No. 352,072.

To all whom it may oncern:

, Be it known that 1, ROBERT J. Burrows, a citizen of the United States, and a resident of Buchanan, in county of Berrien and State of Michigan, have invented certain new and useful Improvements in Metal lVheels, of which the following is a spec1fication, reference being had to the accompanying drawings.

My invention relates to metal wheels for motor vehicles, and has for its object to provide an improved wheel especially su1table for motor trucks and other vehlcles designed to carry heavy loads. To th1s end it consists incertain improvements in the construction of the wheel rim, and in certain improved combinations, all ofwhich improved features are fully hereinafter described in connection with the accompanying drawings. What I regard as'new is pointed out in the claims.

l in the accompanying drawings,-

, Fig. 1 is a sectional view of my improved wheel taken on line 11 of Fig. 2;

Fig. 2 is a side elevation thereof, certain 7 parts being broken away; and

. Fig.3 is a sectional detail showing more particularly an improved hub construction.

My improved wheel comprises a rim 4: in the form of an annular band provided between its margins with a circumferentially disposed inwardly oflset portion or bead 5 formed by deflecting or bending inwardly the intermediate 'portion of the material, preferably at or near the transverse center of thewheel. ft is best to make this in- Wardly projecting bead continuous around the wheel so that it is annular, as illustrated in 1, although my invent on is not limite to making. it continuous in all cases.

lhis bead serves to brace and strengthen theintermediate portion of the rim, leavin its outer surface fiat so that it is well adapted to receive an outer rim, preferably in the form of a demountable tire carrying rim such as are ordinarily used on motor vehicles.

6 indicates the hub of the wheel, two

' forms of which are shown. In the form shown in Fig. 1 the hub 6 is provided with an intermediate annular portion 7 carrying ah outwardly projecting annular flange 8, at opposite sides ofwhich are fitted the inner marginal portions of two outwardly diverging discs 9, 10 which connect/the hub with the rim 4. These discs are held in place by collars 11, 12 fitted upon the intermediate portion 7, and secured together by'bolts 1" 3 so that they clamp the inner margins of the discs 9, 10 tightl inplace. \Vhere the wheel is used for braking purposes it is pro vided with a. brake drum 14 secured upon the intermediate portion 7 outside of one of the discs, as 9, and held in place by one of the collars, as 11, as shown in Fig. 1.

In Fig. 3 I have illustrated a hub of im-' proved construction composed of telescoping members 19, 20. These members when united form a hub similar in a general way to that shown in Fig. 1. The member 19 carries a flange 21 similar to the flange 8 in that it serves as a means for connecting the discsI9, 10 and the brake drum 1 1 tothe hub. The member fits closely upon one end of the member 19 and is provided at its inner margin with a radial flange 22 which fits over the inner marginal portion of the disc 10 and takes the place of the collar 12 shown in Fig. 1. With this type of hub [the collar ll and bolts 13 shown in Fig. 1 are employed and perform the functions .So far as I am aware I am the first in the art to provide a wheel .rim' of the character v v described withan inwardly projecting annular rib betweenits margins, or to form such rib by means. of a. bead integral with the rim,'and the claims hereinafter made] are, therefore-,to be construed accordingly.

What Iclaim as my invention and desire to secure by LettersPatent, is:

1. A metal wheel-comprising in combina tion an integral rim having an intermediate inwardly projecting annular rib, a hub, and

' outwardly diverging ineans fixedly con-i connected with the hub and with the rim at- 'nected with the hub and with opposite sides of said rib.

2. A metal wheel comprising in combina tion an integral rim having an intermediate inwardly projecting annular rib, a hub, and separate outwardly diverging discs fixedly the rim 7 opposite sides of said rib.-

3. A metalwheel comprising in combination an integral rim having its outer surface pressed inwardly circumferentially to form an inwardly projecting bead between its marginal portions, a hub, and outwardly said head.

, 4? A metal wheel comprising in combina-' .ofsaid discs.

tion an integral rim having its outer surface continuously around the rim between its marginal portions, a hub, and out- 'wardly diverging means fixedly connected with the hub and with the rim-at opposite sidesof said bead. a

' .5. A metal wheel comprising in combinarim having inwardly extending flanges opposite to and abutting against the outer edges ROBERT: J. 'BURROWS.

- tion an integral rim having an intermediate inwardly projecting annular rib, a hub, and separate outwardly diverging 'discs fixedly connected with the hub and with the rim' at I opposite sides of said rib, the margins of the diverging means fixedly connected with the hub and with the rim at opposite sides of
